Luke 1 - Zechariah's voice was restored after his act of faith and willingness to break from tradition.
Luke 2 - Even though Jesus walked in deep revelation, he submitted to his earthly authority. Reminds me of when Samuel. Although he was God's chosen prophet, he submitted to Eli the priest in humility.
Luke 3 - John's message was a message of repentance. He also explained how repentance works itself out in areas of social justice. That's awesome!
